Whether we are sitting in an air-conditioned room or travelling in any vehicle, the application of thermodynamics is everywhere. We have listed a few of these applications below:

There are four laws of thermodynamics and are given below: In the next few sections, we will discuss each of the laws of thermodynamics in detail. Zeroth Law of Thermodynamics The Zeroth law of thermodynamics states that if two bodies are individually in equilibrium with a separate third body, then the first two bodies are…

Calculate ΔG at 290 K for the following reaction: 2NO(g)+O2(g)+2NO2(g) Solution: Given: ΔH = -120kJ and ΔS = -150JK-1 To make the unit of ΔS the same as ΔH, we have to convert the unit of ΔS as follows:ΔS=−150J/K(1kJ=1000J)⇒ΔS=−0.15kJ/K We know that,G=U+PV–TS⇒ΔG=ΔH–TΔS So,ΔG=−120kJ–(290K)(−0.150kJ/K)⇒ΔG=−120kJ+43kJ⇒ΔG=−77kJ Therefore, ΔG is -77kJ.

Thermodynamic properties are defined as characteristic features of a system, capable of specifying the system’s state. Thermodynamic properties may be extensive or intensive.

Enthalpy is the measurement of energy in a thermodynamic system. The quantity…

Thermodynamics has its own unique vocabulary associated with it. A good understanding of the basic concepts forms a sound understanding of various topics discussed in thermodynamics preventing possible misunderstandings. System A thermodynamic system is a specific portion of matter with a definite boundary on which our attention is focused. The system boundary may be real…

Thermodynamics is classified into the following four branches: Classical Thermodynamics In classical thermodynamics, the behaviour of matter is analysed with a macroscopic approach. Units such as temperature and pressure are taken into consideration, which helps the individuals calculate other properties and predict the characteristics of the matter undergoing the process. Statistical Thermodynamics In statistical thermodynamics,…

The distinction between mechanics and thermodynamics is worth noting. In mechanics, we solely concentrate on the motion of particles or bodies under the action of forces and torques. On the other hand, thermodynamics is not concerned with the motion of the system as a whole. It is only concerned with the internal macroscopic state of…
